The review of power generation from integrated biomass gasification and solid oxide fuel cells: current status and future directions

How to Compute Whether Biomass Fuels Are Carbon Neutral

“…Given its immediate technological availability [1][2][3][4][5][6][7][8][9], biomass energy has been playing a key practical role for decades already, and was conceptually supported by the traditional assumption of its carbon neutrality: under sustainable conditions, carbon dioxide emitted during combustion was held to be equal to its absorption during plant growth [10][11][12][13][14][15][16][17]. However, in order to clarify conditions of carbon (C) neutrality quantitatively and more reliably [18][19][20][21][22][23][24][25][26][27][28][29][30][31], it became necessary to model the annual natural C cycle globally and to consider its changes as a result of steadily growing large-scale biomass strategies [32][33][34][35][36][37][38][39][40]. Because a recent publication [41] found much interest in readership, this article dwells still deeper into the dynamism of C flows and their alterations after biomass fuel extraction from the natural C cycle.…”

Residual Biomass Gasification for Small-Scale Decentralized Electricity Production: Business Models for Lower Societal Costs

“…Most of the reviewed papers considered the production of electricity by syngas-fed Internal Combustion Engines (ICEs) or gas engines. The integration of biomass gasification with fuel cells, especially solid oxide fuel cells (SOFCs), is presented in [55] as a promising although still experimental technological option for electricity production at a small scale because of its high efficiency and fuel flexibility. However, the development stage has not reached commercialization yet; therefore, investment costs are still very high, and some technical barriers are still being addressed by research.…”

“…From among the available energy-related strategies, and given its immediate technological availability [4][5][6][7][8][9][10][11][12], biomass energy has been playing a key practical role for decades already, and was conceptually supported by the traditional assumption of its carbon neutrality: under sustainable conditions, carbon dioxide emitted during combustion was held to be equal to its absorption during plant growth [13][14][15][16][17][18][19][20].
